Abstract
Vibration limiting apparatus for use in supporting devices sensitive to vibration embodies an outer supporting container. A vibration dampening liquid within the outer container dampens vibrations transmitted between the outer container and an inner buoyant member. The inner buoyant member supports the vibration sensitive device and floats freely within the outer container. Oppositely disposed magnets mounted on adjacent surfaces of the inner buoyant member and the outer supporting container urge the inner buoyant member toward a position so that it is supported by the dampening liquid in spaced relation to the adjacent inner surfaces of the outer container.
